| Jun-15-07 | | Ragh: <greensfield> Good analysis, both pawn-captures-knight on 19th move for black (exd5 and cxd5) loses black's queen instantly and leading to mate in a couple of moves. In fact, 20.Bb5 after 19...cxd5 is a !! move. |
|
| Jun-15-07 | | schnarre: <greensfield> Good analysis mate! |

| Jun-15-07 | | newton296: found the first move e6 on instinct, but couldn't find the follow up Nxd5!! wish I did as the move is just pretty. lots of thought required to get Nxd5 here as the knight can be taken 4 ways so you have to refute them all before finding it! I guess max ( a gm )couldn't find it either so I don't feel that bad that I missed it. |
|
| Jun-15-07 | | newton296: <yourang> 18)...Nxd5 is refuted by Bxg6 mate!! Blacks king is suddenly caught in the bishops and Q crossfire!! pretty mate I must say. |
|
| Jun-15-07 | | newton296: I like this puzzle. The finish is just so sweet. Penrose must have felt great to find this combo. |

No its not, the f7 pawn is still there. |

 | | fm avari viraf: What a mind-blowing combination! I think, 16.e6 is just a 1 star difficulty but 17.Nxd5 is a 4 star difficulty! Now, Black can capture the gallant Knight on d5 with 17...exd5, cxd5, Nxd5 & Qxd5 but unfortunately all spell disaster for Black. If 17...exd5 then 18.Rxe7+ wins, if 17...cxd5 then 18.Bb5 Nc6 19.Bxc6 Qxc6 20.Qxe7#, if 17...Nxd5 then 18.Bxg6+ wins, if 17...Qxd5 Qxe7#. The text move also wins 21...gxf5 22.Rxe6+ [22...Qxe6 23.Nc7+ ]Kf7 23.Re7+ & wins. |
|
| Jun-15-07 | | ChesterTheJester: Nxd5 = astonishing! en pris in four different ways, but can't be taken. I agree with FM Viraf about e6 being quite an easy move however,the Knight on e7 being the only defender of g6 makes e6 the decisive way to blow black's Kingside apart! |

| Jun-15-07 | | Crowaholic: The pawn sac on e6 to weaken g6 was easy enough to find, but I had a hard time figuring out a better followup than 19. Bxe7 Qxe7 20. Bxg6+. Finally, it occurred to me that in case of 19. Nxd5, no matter how Black recaptures, all hell will break loose: 19. ..exd5 20. Rxe7+ or 19. ..cxd5 20. Bb5! or 19. ..Nxd5 20. Bxg6+ Qf7 (only move) 21. Rxe6+ Kd7 22. Qd6+ Kc8 23. Bxf7 which is totally crushing, or of course 19. ..QxN 20. QxN# which is just foolish. If Black does not recapture, White has the Rxe6 and Nc7+ threats. I did not consider many lines here, to be honest, because I was convinced that I had found the solution and it's already getting late. I looked at the game as played, and when I saw 19. ..Nf5, I figured that this move does not stop the powerful 20. Rxe6+ threat, and decided that this would be a good follow-up. Black doesn't seem to have anything better than 20. ..Qxe6 and then 21. Nc7+ should be winning. If the king takes the knight after 22. Nxe6, then Re1+ and his majesty is in big trouble. This should at least be enough to collect some more material and eventually finish Black off. |

| Jun-15-07 | | bogo78: this puzzle showed me once again how important the order of moves is. I had looked at 18 Nxd5 Nxd5 (the only valid capture) 19. e6 Qc7 20 exf7 Kxf7. And now i thought white is winning the ♕, overlooking the fact that the ♘ on d5 covers e7... Of course this shows I completely missed the point which was wakening the g6 square. The moves were almost very easy guesses but some analysis was required to determine the right order. Since mine was flowed, i missed this one...Nice puzzle! |
|
| Jun-15-07 | | Crowaholic: <syracrophy: 20.Rxe6+ is nice, but 20.Bxf5 mates the K in a few moves> Err, how so? According to my computer, there is no quick mate (up to 8 moves) with play continuing e.g. 20. Bxf5 gxf5 21. Rxe6+ Qxe6 22. Nc7+ Kd7 23. Nxe6 Bf6  In case of 23. ..Kxe6, White has a mate in five, but this move is not forced. Do you know better moves which force mate more quickly? |
|
| Sep-08-11 | | chillowack: 19.Nxd5!! is one of the best moves I've ever seen: a real thing of beauty. Deserves an extra exclam. |

 | | perfidious: Penrose scores a neat win in his favourite Goering Gambit with the seemingly impossible 19.Nxd5. Bet his opponent was feeling Blau after that move. |
|
| Sep-08-11 | | chillowack: He was feeling Blau to the Max. |

| Apr-08-16 | | dfcx: The major weakness is the black knight, only if the white king pawn were not there... 18.e6 fxe6 (queen move? exf7+).
19.Nxd5!
A. 19...cxd5 20.Bb5 Qxb5? 21.Qxe7#
B. 19...exd5 20.Rxe7+ wins the queen
C. 19...Nxd5 20.Bxg6+ Qf7 21.Rxe6+ mates
D. 19...Nf5 20.Rxe6+ Qxe6 21.Nc7+ wins the queen too. |

 | | An Englishman: Good Evening: Checking the database, I can't blame Blau for ducking the gambit--Penrose scored very well with both the Goring and the Danish. However, if you decline a gambit, you still must know the theory, and 4...Nf6? was not the right choice. |
|
| Apr-08-16 | | Granny O Doul: That's a hell of a move. Blau beaten and humiliated. |
|
| Apr-08-16 | | patzer2: An alternative solution to today's Friday puzzle is 18. h3 Kf8 20. hxg4 (+4.27 @ 19 depth, Deep Fritz 15). For a Black improvement, I like the computer suggestion of starting early in the opening and replacing 5...Ng4?! 6. cxd4  (+0.68 @ 19 depth, Deep Fritz 15) with 5...Nd5 6. cxd4 = (-0,01 @ 20 depth, Deep Fritz 15). |
|
| Apr-08-16 | | ndg2: Switched the move order (first Nxd5 and then e6), but black will escape here because the knight can be taken with that move order. It's not possible with the game continuation. |
|
| Apr-08-16 | | diagonalley: darn... got the first move, but missed the follow-up... <diagonalley>: nul points :-( |

| Apr-08-16 | | alshatranji: alshatranji: Fascinating problem. I think it was yesterday that someone said something about chess being like music. You know the keys and notes, etc, but you need to play them in the right combination and tempo (or something like that). Today's puzzle is a perfect example. I thought of e6 immediately. Black has to capture, but after that nothing is decisive. Re1 is fine, but Black has the time to protect his pieces; g6 is weakened, but it's still protected by the knight. Then I found Nxd5, which looked great: Black cannot capture with the pawn, but then the knight is protecting d5. Here I briefly considered and dismissed Nb5. It looks elegant: the Knight cannot be captured for the same reason, but there is no real threat. I had to go over the lines again, and at one point they started to coalesce. I think the key factor is that the black knight is protecting both g6 and d5, so you can remove it from one to attack the other. In other words, you have to play the two lines, one after the other. Then everything came into focus, a blinding flash, and all was clear. |
